武汉地区露地宿根花卉引种及抗性观测

Introduction and Observation of Resistance of Outdoor Perennial Root Flowers in Wuhan

在武汉对引进的38种优良露地宿根花卉品种的生物学特性及抗逆性(耐热、抗寒、抗旱、抗病虫害)进行了连续3年的试验观测。结果表明:大多数品种的观赏性无退化现象,适应武汉的气候条件,能正常生长发育。

Thirty - eight excellent outdoor perennial root flower species were introduced into Wuhan, their biological characteristics and resistance （heat tolerance, cold resistance, drought resistance, pest and diseases resistance） were observed in Wuhan for con- secutive 3 years. The results indicated that the most introduced species were adaptive to the climate conditions of Wuhan, and their or- namental traits did not degenerate.
